Over the past two centuries, humans have locked up enough water in dams to shift Earth’s poles slightly away from the planet’s axis of rotation 🌍💧 | The construction of nearly 7,000 dams from 1835 to 2011 shifted the poles about a meter in total and caused a 21-millimeter drop in global sea levels. 🌊📉

Through analysis of sulfur isotopes in the well-studied HK-1 drill core, researchers showed that Earth’s largest mass extinction event didn’t wipe out life on land with a single massive volcanic event. Rather, the die-offs happened regionally and progressively over hundreds of thousands of years 🌍💔🌋📉

🌍 New tectonic plate boundary might be forming in Zambia, indicated by gases from hot springs originating deep below Earth's crust.

🌋 Researchers analyzed gas samples from hot springs and geothermal wells in central Zambia, finding helium and carbon isotope ratios consistent with deep mantle fluids, up to 190 km below the surface.

✨ This suggests a tear in the region's tectonic plates at the Kafue Rift, which is part of a larger 2500-km rift zone.

💰 The process is releasing helium concentrations up to 2.3%, attracting industrial interest.

🌍 Scientists believe Earth's mysterious low-frequency "hum," first detected in the 1960s, is caused by ocean swells generated in the Southern Ocean.

🌊 These swells create tiny vibrations that travel through the planet, amplified by interactions with the Earth's crust.

🎤 Melbourne scientist Rohan Byrne recorded the hum and coincidentally captured the rumble of a distant earthquake, highlighting ongoing discoveries about Earth's workings.

Scientists have found evidence that vast amounts of water may be locked deep within Earth's mantle, up to 1,800 miles below the surface, potentially reshaping our understanding of the planet's water cycle and interior structure.

💧 New research identifies two previously unknown iron oxyhydroxides (Fe5O12Hx and Fe7O12Hx) that could store vast amounts of water deep within Earth's mantle.

🔥 These minerals are stable under the extreme pressures and temperatures found near the core-mantle boundary, potentially explaining how Earth retained its water over geological time.

🌍 The discovery suggests Earth's water cycle may extend to the planet's core, impacting tectonic activity and climate regulation.

🌍 A new study published in Nature suggests that changes in Earth's rotation over several decades originate from deep within the planet, driven by three competing mechanisms: gravitational, electromagnetic, and topographic coupling.

🌍 Gravitational coupling, a gravity "torque" between Earth's inner core and mantle, is the primary influence on these multidecadal rotational changes, with the other two mechanisms acting as buffers.

🌍 This research offers a more coherent picture of Earth's deep interior and provides constraints on its properties, explaining why the length of a day has subtly changed by milliseconds between the early 1970s and 2021.

Researchers traced decades long wobbles in day length to gravity pulling between the spinning inner core and the mantle above it, not magnetism as long assumed.
